It will also be seen that by virtue of Fig. 4. After the sash has been elevated to the desired height the keyE should .be released, when the spring d will cause thecam D to turn into the position shown in red lines at Fig.4, which will cause the arm B to be thrown out, as shown in red, until the block 0 comes against the side or edge of the sash. The tendency of the sash to descend will then cause it to press against the cam-block C (or G) and turn it tightly up against it (thesash) and firmly sustain it. hen it is desired to lower the sash, thekeyEmust be again turned and the lever B thrown back into the position th shown by-black. lines'at Fig. 4. Whenthe sash is down, the key may be turned in the reverse direction, which will force the cam G (or G) tightly against the sash, so that it cannot be raised; a

It will be seen that with an apparatus such as mine the sash may be readily and securely held at any elevation and securely locked the swinging lever carrying the retainingcam, the shrinkage or wabble of the sash in the frame will not affect the perfect operation of the apparatus, since the cam on the vibrating arm or leverBis always forced out against the sash before the clamping action of the retaining-cam commences; and it will also be seen that my improved apparatus, possessing ing very economically made, and does not re-- quire any mutilation of the frame or sash. a

Having described the construction and op- ,eration of myimproved sash retainer and lock,

what I claim therein as new, and desire to secure by Letters Patent, is-

1. The swinging lever B, in combination with the cam D, with its arm D'and the'spring d, orits equivalent, and the key E, the whole constructed and operating as described, for

e purpose set forth.

Forming on the pivot end of the arm B an eccentric-hub, z, in combination with the arm D of the spring-cam D for retaining the vibrating arm within the case A, as hereinbefore described.

, 3. The combination of an eccentric clamping-dog or double cam-piece, C, or its equiva-- lent, with the vibrating spring-actuated lever for arm B, substantially as for the purpose set orth.

In testimony whereof I have hereunto set my hand and aflixed my seal this 15th dayof March, 1862.
